摘 要: | 对常熟市虞山林场杨梅园土壤动物群落的构成进行了调查,共获得土壤动物样本1 405个,隶属于4门、7纲、22类。优势类群为蜱螨目和弹尾目2类,占个体总数的90.72%,构成了该地区土壤动物群落组成的主体;常见类群为线虫,占全部土壤动物个体数量的4.76%;其他为稀有类群。3样地环境中土壤动物群落结构分析表明,个体密度为样地3〉样地2〉样地1;类群数和土壤动物多样性指数(H’)为样地1〉样地2〉样地3;均匀度指数(J)为样地3〉样地2〉样地1;优势度指数(C)为样地3〉样地2〉样地1。不同群落的相似性(q)分析表明,样地1与样地2、样地1与样地3、样地2与样地3的q值均大于0.5且小于0.75,表现为中等相似。土壤动物垂直分布有明显的表聚现象。

Abstract: | A preliminary study on the diversity of soil invertebrate communities was conducted at Bayberry Park.A total of 1 405 samples of soil animal was obtained,belonging to 4 phylums,7 classes and 22 taxa.The dominant groups were Acarina and Collembola,which amounted to 90.72% of total individuals and composed the main component of soil animal cluster in the region;Common groups were the Nematoda sorts,amounting to 4.76% of the total.Other types were rare groups.Three kinds of ecological environment of soil animal community structure analysis showed: the density order was artificial plot3>plot2>plot1;Number of groups and diversity(H') were artificial plot1>plot2>plot13;Evenness(J) were plot3>plot2>plot1;Dominance(C) were plot3>plot2>plot1.The analysis of the similarity(q) of different group suggested that the similarity(q) of soil invertebratesthe plot1 and plot2,plot1 and plot3,plot2 and plot3 were moderate similar(0.75>q>0.50).Vertical distribution of soil invertebrate was concentrated in the surface. |
